Abstract
The disclosure relates to a method for detecting a standstill of a vehicle, said method comprising a step of filtering, a step of normalizing and a step of observing. In the filtering step, an acceleration value in a first axis of the vehicle and a rotational speed value about a second axis of the vehicle, oriented orthogonally to the axis, are filtered using a filter specification in order to obtain a filtered acceleration value and a filtered rotational speed value. In the normalizing step, the filtered acceleration value and the filtered rotational speed value are normalized using a normalization specification in order to obtain a normalized acceleration value and a normalized rotational speed value. In the observation step, the normalized acceleration value and the normalized rotational speed value are observed using an observation specification in order to detect the standstill.
